VEHICLE-WHEEL.`

To all whom it may concern:

Be it known that-I, CHARLES C. Wars, a citizen of the United States, residingat Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in VehiclelWheels, of which the following .is a specification.

My resent inventionis an improvement u on tiie vehicle wheel shown, described and c aimed in my application for patent on 1m .u'ovements in vehicle wheels filed Decemer 24th, 1914, serai No. safes.

It is the object of the'prese improvement to provide novel armor interposed between the outer casing and the inner pneumatic tube; further to provide noviel means whereb cooling air-chambers are f'formed between t e outer 'casing and the yinflatable inner pneumatic tube of the tire,v having communication with the outside atmosphere for providing circulation of 'air in the airchambers and cooling the tire; and, further `to provide means whereby the admission of -`water and deleterious foreign substances y rim and intoi the air-chambers is prevented.

The invention will be further readily uncicrstood from the following description and claims, and from the drawings, in which latter:

'Figure 1 is 'a side elevation of my improved device, partly broken away for. better illustration of the parts.

annular bases 23, 24, o f the casing. The

detail showing the air-passzuaie` Patented J an. 15, 1918.

This cushion-member is of resilient vsubstance, as rubber, and may have an inner lining 19 of fabric embedded therein.

In the present exemplification of my invention the casing is held in place means of annular Hangs 21, 22, which erect with annular ange 21 Vextends integral rom an annular rim 25 which is provided with an annular groove 26 in which an annular splitring 27 1s received. The annular flange 22 is on an integral ring 28 which is held about the rim 25 by means of the split-ring 27. A usual annular apron 29 is received between tbe bases of the outer casing and the inner tube for protectingthe pneumatic tube of the tire. The inner portion of the casin preferably has fabric strips 30 embedde therein.

The rim 25 is suitably attached to the body of the wheel. It is exemplied'as a demountable rim, being held in place about an annular felly-rim 31 secured to the felly of the wheel, as by the 'annular inclined connection 32 at one side thereof and the annular clamp-ring 33 at the other side thereof, the latter clamped in place by vWithin the annulus ofthe .inner inflatable pneumatic tube when inflated and4 past the points of contact of the annular *flan es 21,

22, in the outer casing, so that/sai inner ends are located to substantial extent be tween the annular bases 23, 24:,V of the cas-A ing, which extend to substantial extent -toward each other, and said innerfinilatable4 pneumatic tube when inflated in "lines per`` pendicular to the taxis' of rotation of the wheel.

The horns gradually increase in crosssection toward-the side portions of the cushionmember- 18, as shown at 38. The outer peripheral portion of the armor isfformed cross-sectionally to form a Vsubstantially T- shaped headbcomprising a. stem'll and latmfr erally extending wings '42 forming recesses 43 arranged annularlyabout the armbr, the

inner walls of said recesses being formed b y webs 44 between said stem and horns.

The recesses 43 form channels extending annularly between the horns 36 and the annular outer peripheral or tread portion of During use of pneumatic tires, theltires, in

practice become heated. I have 'therefore provided means whereby a cooling agency may be introduced into the tire, which I accomplish by employment of the channels 43 which form substantially annular chambers between the armor and the outer casing of the tire. I provide means whereby a current of cooling agency is passed into and out of said chambers. For accomplishing this I prefer to employ cross-channels 45 which communicate with the channels 43 and preferably pass along the horns 36 in direction toward the axis of rotation of the wheel or arranging their inner ends away from the tread portion of the wheel, that is, toward the location of the securing means on the wheel for the tire, so as to remove the openings-at the inner ends of said cross-channels from the'tread portion of the tire in order to reduce the liability of undesirable substances being received in said channels.

In my preferred construction the outer faces of the innerportions 'of the horns 36 are provided with'preferably annularly arranged grooves 46 for forming passages for the cooling agency, for instance air, between said horns and the outer casing. The chan- 4nels 45 communicate with the grooves 46.

,The outer casing is provided with an aperture or apertures 47 adjacent to the attaching means thereof, forming passages ar- Uranged to communicate with the grooves 46.

The grooves may be extended any desired distance annularly about the armor so as to insure registry between said grooves and the passages- 47 vwhen the armor is located in the outer casing. The grooves are shown in the armor, although they may, if desired, be

located in the inner face of the outer casing.

The passages 47 are arranged to have communication jwith the 'outside atmosphere, accomplishedpreferably in manner'to prevent the passing of water, dust or the like, into the cooling passage of the tire. I exemplifythe passages 47 as arranged to communicate with holes 51 in the rim 25, grooves 52 being between the passages 47 and holes 51, shown in the outer face 0f the rim.

There is an annular space 53 between the rims 25 and 31, with which the holes 51 communicate. One or more passages 54 are provided through the rim Bland the fellyy 14, four of these passages being `shown.A

These passages are 'preferablyclosed by a water and dust-arresting'substance, for instance a suitable fiber. A body 55 of the water and dust-arresting substance is shown located in the passage and is arranged to arrest the water, dust and the like, but permits the passage of air.

The channels 43, 43, are connected throu h vwardly therefrom at points adjacent t0 the compressed portion. When the compressed portion leaves the ground it will `again expand and thereby draw in air, for causing a current of air to pass through the, ichan nels and passages, thereby cooling the tire and preventing excessive heating thereof.

My improved device forms a tire which for all practical purposes is puncture proof. The armor further provides means render ing the tire non-collapsible. The horns of the armor extend past the contact-points between the fianges of the tire securing means and the outer casing, and thereby prevent blow-outs, as the armor acts as a support at the inner face of the outer casing. which covers the weakened portions of the outer tire and receives the stress of the pressure `of the inner tube.

The load pressure o'f the wheel is directed against the annular T-head of the armor which .extends annularly outwardly from the webs `between theba-ses of the horns at either side of the armor. The resilient webs aid in resiliently resisting the load pres sures acting upon the T-head, which -is of resilient materiaL for cushioning the tire independent of theinflatable inner pneumatic tube. The load pressures upon the resilient headv and the resilient webs further act to resiliently spread the side-s ofthe armor, theA inner ends of the horns of the armor resting upon the faces of the outer casing and acting as an inner anchor for the horns,

Having th`us fully described my invention, what I claimab new and desire to secure by Letters Patent, is:

l. In a vehicle wheel, the combination of a casing, an inner pneumatictube, and an armor interposed between said casingand inner pneumatic tube, said armor being substantially crescent-shaped in cross-section municating with said first-named channels leo projecting laterally crosswise of and spaced y from said cross-wens.
